FORECAST
THIS WEEK
Humidity is back. It is rolling in this morning and it’ll camp out over South Texas all week long. This means we’ll be in more of a spring-like pattern of morning clouds (lasting until about noon) and afternoon sunshine. Plus, it’ll be warm. Highs will be in the mid-70s to near 80 through at least Saturday.
